Justin Bieber & Ariana Grande In ‘I Really Like You’ Video

OMG! All of our faves have compiled into one amazing lip sync video, and we can’t even deal with the star-studded action happening in it!

Not only did Justin, Scooter, and Kendall team up for Carly Rae Jepsen’s “I Really Like You” video, but other stars like Lance Bass, Frankie Grande, CL, Keaton Stromberg, and so many more are also featured. But, of course, the best part is watching a very shirtless Justin prance around with his pals — like Ariana and Kendall!

The video starts off with Justin, Ariana, and Frankie dancing and singing alone in a dressing room. Then, just as things get good, they get even better — because suddenly Justin is dancing shirtless by the pool with his dad!

But, things get interesting when Kendall joins the fun, and her introduction into the video comes via Justin’s shoulders. Yes, that’s right, Justin carried Kendall on his shoulders while they were all alone!

In between shots of Ariana hamming it up with her tour crew and dancers, Justin and Kendall get close on his webcam and even bring his dog, Esther, into the lip syncing. So cute!
